In any rotating machinery system, the bearing has traditionally been a crit ical member of the entire system, since it is the component that permits the relative motion between the stationary and moving parts. Depending on the application, a number of different bearing types have been used, such as oil-lubricated hydrodynamic bearings, gas bearings, magnetic suspensions, rolling element bearings, etc. Hydrodynamic bearings can provide any desired load support, but they are limited in stiffness and the associated power loss may be quite large. Gas bearings are used for high-precision applications where the supported loads are relatively light, bearing power losses are very low, and the rotati...
This book presents the select proceedings of the 1st International Conference on River Corridor Research and Management (RCRM 2021). It describes various topics on fluvio-hydro-ecological processes of river systems. The topics covered include river dynamics and morphological changes, river health and ecological aspects and satellite remote sensing for river corridor studies. The book also discusses the morphological behavior of gravel and sand-bed rivers, hydrological and hydraulics modeling and other important aspects of riverine ecology. The book will be a valuable reference for research scholars, academicians, river scientists and practitioners working in the areas of river science.
This book of abstracts presents the extended abstracts received and accepted for presentation in the International Conference on Modeling of Environmental and Water Resources Systems.
Object Detection with Deep Learning Models discusses recent advances in object detection and recognition using deep learning methods, which have achieved great success in the field of computer vision and image processing. It provides a systematic and methodical overview of the latest developments in deep learning theory and its applications to computer vision, illustrating them using key topics, including object detection, face analysis, 3D object recognition, and image retrieval. The book offers a rich blend of theory and practice. It is suitable for students, researchers and practitioners interested in deep learning, computer vision and beyond and can also be used as a reference book. The comprehensive comparison of various deep-learning applications helps readers with a basic understanding of machine learning and calculus grasp the theories and inspires applications in other computer vision tasks. Features: A structured overview of deep learning in object detection A diversified collection of applications of object detection using deep neural networks Emphasize agriculture and remote sensing domains Exclusive discussion on moving object detection
The Hindu Kush Himalayan (HKH) region is highly vulnerable to earthquakes and water-induced disasters. This fragile mountain region is under tremendous stress from climate change and land-use degradation that has accelerated flash floods, river-line floods, erosion, and wet mass movements during the monsoon period and drought in the non-monsoon period. Against the backdrop of intensifying disasters and in the absence of a focused documentation of disaster risk reduction issues in the HKH region, this volume presents a comprehensive body of knowledge. The main purpose and objective of this publication is to connect existing data, research, conceptual work, and practical cases on risk, resilience, and risk reduction from the HKH region under a common analytical umbrella. The result is a contribution to advancing disaster resilience and risk reduction in the HKH region. The book will be of special interest to policy makers, donors, and researchers concerned with the disaster issues in the region.
This fourth edition presents clinicians with the most recent developments in ultrasound in obstetrics and gynaecology. Beginning with an introduction to the physics, machines and measurements used in ultrasonography, the following sections provide in depth coverage of its use in diagnosing and managing different obstetrical and gynaecological conditions. The text also covers infertility, interventional procedures, other methods in radiology and legal and ethical issues. Presented in an easy to follow, bulleted format, this new edition includes numerous ultrasound images, illustrations and tables, as well as a quick reference appendices section which includes AIUM (American Institute of Ultrasound in Medicine) Guidelines and protocols from Thomas Jefferson University in Philadelphia.
